IMPROVEMENT IN SPRING BEDLBOTTOIVIS.

Specification forming part of Letters Patent No. 131,743, dated October1, 1872.

To all whom it may concern:

Be it known that'I, WILLIAM Z. COOKE, now of New Britain, county ofHartford and State of Connecticut, have invented certain new and useful`Improvement in Spring Bed- I1?ottom5-and to enable others skilled inthe art to make and use `the saine, I will proceed -to describe itsconstruction, referring to the drawing,'in whichthe same lettersindicate like parts in eachof theflgures.

The nature of this invention consists in the manner of construction, andcombining the frame-work and webbing that it can be easily and quicklytaken apart and replaced readily at will; the object of which is .toproduce a cheaper, stronger, andmore durable mattress, and, at the sametime, produce a superior article of manufacture and trade.

corners. The upper side plate is removed to show the shape of the tenonends of the rails or frame. d are pins, arranged in said rails orframe-work to receive or secure the links f of the web, which are madeof rsuitable sized wire, and having the ends made hook or eye form nearone corner of each link, and

these links connected at the corners by spiral springs g around theouter edge of the Webbng. I sometimes hook the eye h of one end of thesprings g onto the pins d, and the other end e to the links f, and theintermediate links,

which make up the surface of the mattress, I v

connect by links i, or short pieces of chain, thus making up theentire'Web-surface of the mattress. The side rails of the frame a aremade straight, and when made of metal are made of a right-angle shape tosecure lightness and strength, and the sockets formed in thecorner-connecting pieces lo are made of corresponding shape to receivethe angleshape rail. This rail may be adjusted in or out of the socketlby a pin passing through the corner. Connecting pieces 7c are made ofcorresponding shape to receive the angleshape rail, and this railadjusted to its place by a pin, Z, passing through the connection 7c andthe angle rail. The end rails d are made straight or curved, the objectof which is to round up the center or surface of the mattress. Thus amattress is produced which can almost instantly b e taken apart andpacked in a very small space, and can be quickly put together again,when desirable, rendering it cheap of manufacture, strong, and durablefor use.

I believe I have thus shown the nature,

construction, and advantage of this invention so as to enable othersskilled in the art to make and use the same therefrom.

What I claim, and'desire to secure by Let- I 1. The combination of linksf, spiral springs g, links or chains i, substantially as and for thepurpose set fort-h.

2. The combination of the framework a d and connecting-pieces with theweb composed -of the links and springs, as described.
